J. W. YOST AUTOMOBILE DIRECTION SIGNAL Filed April 28. 1927 indicator "w JOHN WASHINGTUN YQST, OE NEWPGRT NEYR E, VIRGINIA.

AUTOIEGBILE DInEOTIUN SIGNAL.

Application filed .april 538, 192?.

My invention rela es to a si nal devic to ind cating when a vchic about to and in which directiorn also stopp ng starting.

The object of my iiivention is to device oi? thi t kind which wil stitute :tor the arm n A iiiirther object or my i entiou is to providean indicator oi th s type in which the normally ,he '1 in such pesi cannoa 1 con i'roin whieles ap- )PU- tion that lo preaching from the trout or rear and to i vide means whereby the signal can he on operated to swing the indicator to proj,ect

laterally from the vehicle so t it it be readily seen from the rear or tront or the vehicle.

A further object of my invention is to provide means for turning the indicator at right angles from its normal inactive position, while it is being moved to assume its lateral or signal position, whereby a relative thin indicator may be used to adapt it to lie close against the vehicle when in inactive position.

A further object of the invention to provide means whereby the indicator can be operated from within the vehicle be it an open or closed vehicle; and with these and 39 other objects in view, my invention consists of the parts and combination otparts as will be hereinafter pointed out.

In the drawings:

Figure 1 is a top plan view of a signal de vice embodying my invention, parts being in section and a part of the housing reniovec Figure 2 is a sectional view on the line 22, Figure 1.

Figure 3 is a detail sectional View on the line A--A, Figure 1.

The reference numeral 1 designates a housing of suitable construction provided in one of its walls with an elongated slot l in which the rod 5 of the signal 4: moves as it is moved into and out of operative position. The housing is provided with a suitable cover.

The housing 1 is provided with a journal bearing 8 in which a shaft ll is journalied, said shaft having an operating handle 11, positioned, when the device is assembled. on a vehicle, within the vehicle. ihis shaft is provided with a plurality of holes 7 which will be again referred to.

A gear 2 having a hub provided with a collar having a series of recesses 6, said re cesses being of diiierent depth as shown in that with Serial No. 187,419.

Figu e 2 which cooperating with the holes '3 in the shaft i1 enables one to a wide variation oi' :uljiustnients oi the shait to accoininod: ing thickness oi doors or other pa !e to which the do vice is ttaehed; for ii anco, let us suppose the pin 12 in the recess 6, and one he holes '7, shown, the length a the Hie ti .x

1 aka 1 con :i not be corrected by iilacing the 1 12 in the next succeeding hole 7. This c by placing the pin in one o" the other .ho recesses G which is found to be the pr er one. (it course in material adjusti the pin 12 is moved to sueceeding hole. T, from which it will be seen that a wide variation of take ups of the shaft ll can be made. The pin 12 keys the gear 2 to the shaft 11 A join-rial 3 is secured to the housing at right angles to the shaft 11 as shown in Figure 2, on which is journalled the gear wheel 8 adapted to mesh with the gear 2. As will be seen, the teeth of gear 3 do not extend entirely around the periphery of the gear and in the interrupted portion of the gear 1 provides recess 5 adapted to receive the inner end of the signalrod 5, a coiled spring 1! being around the end of the rod 5 within said recess 5 one end of the spring being anchored to the rod, while its other end is anchored to a wall of the recess; a pin 16 is secured to and projects beyond one side of the rod 5 and is adapted to contact with a cam 18 which is mounted rigidly. on the wall oi? the housing. 1

As shown in Figure 3, one wall 01" the housing is provided with ball seats 13, while the gear 3 is provided with a ball brake or lock 14 held to position by the spring 15 the purpose of which is to hold the indicator in. the position in which it is set and insure the indicator being set in the proper position.

In operation the shaft 11 is revolved by the handle 11 which in turn rotates gear 2, and gear 8. Before this movement the rod 5 is in a vertical position against the side or the vehicle and the indicator i being of flat thin material is snug against the side of the vehicle and cannot be seen from the front or the rear of the vehicle. Now as the gear 3 revolves the post 5 is moved away from the vehicle in the slot 1 and at a predeteri'nined time the pin 16 engages the chess oi the vehicie cam 18 and by continued movement of the gear 3 the pin rides up on cam 18 thereby revolving the rod 5 until the fiat face of the indicator 4: is at right angles to the vehicle, and extending therefrom so that this flat face is presented to traffic from the rear and front of the vehicle and according to its position gives to traffic a stop, turn, or'other desired signal.

It will, of course, be understood that for night driving I. may place the lights on the paddle.

Hut 1 claim is:

1. A direction indicator for vehicles, comprising a housing, a gear train in said housing, means to operate said train, a rod revolubly secured to one of said gears, a pin extending from said rod, and acam on the housing adapted to engage said pin and revolve the rod relatively to the gear in Which it is mounted.

2. A direction indicator for vehicles, comprising a housing, a shaft journalled in said housing and provided With a plurality of holes therethrough, a gear having a plurality of recesses of varying depth in its hub, a pin adapted to pass through one of said recesses in the hub, a hole in the shaft thereby connecting the gear and shaft, a second gear Wheel journalled in the housing and meshing with the first named gear, a recess in said second gear, a. rod rcvolubly mounted in said recess, means to normally hold said rod against rotation, a pin extending from the rod, and a cam on the housing to raise said pin and thereby revolve the rod relatively to the said second gear, and a signal connected to said rod.

In testimony whereof I affix my signature.

JOHN WASHINGTON YOST.
